Description
i DK 170543 B1 Nærværende opfindelse angår indretninger til et luftopvarmningssystem, eksempelvis til boliger, omfattende en cirkulationsenhed til recirkulation af luft og en luftopvarmningsenhed til opvarmning af luft, før denne tilføres 5 boligområdet.The present invention relates to devices for an air heating system, for example for housing, comprising a circulation unit for air recirculation and an air heating unit for heating air before being supplied to the residential area.
Luftopvarmningssystemer, eksempelvis til boliger, hvori en ventilationsenhed med varmegenvinding kombineres med en cirkulationsenhed med filter og varmeflade, er tidligere kendte. To sådanne systemer sælges for tiden af ABB 10 Flåkt AB under navnene Termovent og Minitemp. I begge disse systemer blandes ventilationsluft med recirkuleret luft i en luftopvarmningsenhed, hvorved cirkulationsluft indtages centralt i boligen.Air heating systems, for example for homes, in which a ventilation unit with heat recovery is combined with a circulation unit with filter and heating surface, are previously known. Two such systems are currently sold by ABB 10 Flåkt AB under the names Termovent and Minitemp. In both of these systems, ventilation air is mixed with recirculated air in an air heating unit, whereby circulating air is consumed centrally in the home.
Med henblik på at begrænse udgifterne til elektricitet 15 i det tilfælde, hvor en varmeflade benyttes til opvarmningsformål, som er den mest almindelige løsning, er det ønskeligt at benytte billig natelektricitet. Med henblik på at være i stand til benytte natelektricitet til opvarmning har det tidligere været almindeligt antaget, at såkaldt vandbåren 20 varme skal benyttes. Opvarmet luft har imidlertid den fordel, at energi kan lagres ved at hæve temperaturen i huset i løbet af natten. Om dagen slås varmen derefter fra, og temperaturen tillades at falde til et vist niveau, sædvanligvis tillades, at dette temperaturfald er omkring 3 til 4“C.In order to reduce the cost of electricity 15 in the case where a heating surface is used for heating purposes, which is the most common solution, it is desirable to use cheap night electricity. In order to be able to use night electricity for heating, it has previously been generally assumed that so-called water-borne heat 20 must be used. However, heated air has the advantage that energy can be stored by raising the temperature of the house during the night. During the day the heat is then switched off and the temperature is allowed to drop to a certain level, usually this temperature drop is about 3 to 4 ° C.
25 Takket være god isolation og effektiv varmegenvinding kan anvendelsen af dyr dagelektricitet i høj grad reduceres.25 Thanks to good insulation and efficient heat recovery, the use of expensive day electricity can be greatly reduced.
Det har vist sig, at for at opvarme et hus elektrisk på denne måde, behøver kun 20-25% at være dagelektricitet. Én ulempe ved øgning af temperaturen i boligen i løbet af natten er 30 imidlertid, at en øget temperatur i soveværelset kan føles ubehagelig.It has been found that to heat a house electrically in this way, only 20-25% need to be day electricity. However, one disadvantage of increasing the temperature of the home during the night is that an increased temperature in the bedroom can feel uncomfortable.
Én måde til at opnå en højere luftkvalitet i soveværelset er beskrevet i svensk patent nr. 7703096-3. Her opvarmes soveværelset udelukkende ved hjælp af eftervarmet ven-35 tilationsluft, dvs. eftervarmet udendørs luft, og de resterende rum med cirkulationsluft, som modtager sin del af DK 170543 B1 2 ventilationsluften via soveværelset, dvs. på "den anden runde". Fordelen ved denne teknik er, at der opnås en højere luftkvalitet i soveværelset, og at nattemperaturen i resten af huset kan hæves med henblik på energilagring, uden at 5 temperaturen i soveværelset bliver ubehageligt høj . Generelt Λ kan temperaturen styres separat for soveværelset. Ulempen ved denne tidligere kendte metode er, at soveværelset afkøles i løbet af dagen, hvis varmen afbrydes, eftersom soveværelserne ikke modtager en del af den cirkulerede luft fra den 10 opvarmede del af huset.One way to achieve a higher air quality in the bedroom is described in Swedish Patent No. 7703096-3. Here, the bedroom is heated exclusively by means of post-heated ventilation air, ie. outdoor heated air, and the remaining rooms with circulating air, which receive their part of the DK 170543 B1 2 ventilation air via the bedroom, ie. on "the second round". The advantage of this technique is that a higher air quality is achieved in the bedroom and that the night temperature in the rest of the house can be raised for energy storage, without the 5 temperature in the bedroom becoming uncomfortably high. In general Λ the temperature can be controlled separately for the bedroom. The disadvantage of this prior art method is that the bedroom cools during the day if the heat is interrupted, since the bedrooms do not receive a portion of the circulated air from the 10 heated part of the house.
Formålet med nærværende opfindelse er at eliminere denne ulempe, som findes ved det tidligere kendte luftopvarmningssystem .The object of the present invention is to eliminate this disadvantage which exists in the prior art air heating system.
Dette formål opnås ved hjælp af et apparatur, som 15 beskrevet i indledningen, med de kendetegnende egenskaber angivet i krav 1.This object is achieved by means of an apparatus as described in the preamble, with the characteristic features of claim 1.
Med apparaturet ifølge opfindelsen opnås den fordel, at temperaturen kan hæves i resten af huset, medens der fastholdes en behagelig soveværelsestemperatur i løbet af 20 natten, og i løbet af dagen kan temperaturen i huset tillades at falde uden at afkøle soveværelset. Med apparaturet ifølge opfindelsen opnås øgede muligheder for en ventilation af boliger tilpasset til behovene og med lavt energiforbrug.With the apparatus according to the invention, the advantage is obtained that the temperature can be raised in the rest of the house while maintaining a comfortable bedroom temperature during the 20 night, and during the day the temperature in the house can be allowed to fall without cooling the bedroom. The apparatus according to the invention provides increased possibilities for ventilation of housing adapted to the needs and with low energy consumption.
Eftersom apparaturet ifølge opfindelsen ikke blot 25 blæser ventilationsluft i form af udendørs luft ind i soveværelset, men også benytter cirkulationsluft, som ikke er fuldstændigt forurenet, kan de specificerede standarder opfyldes trods det faktum, at "for lidt" udendørs luft indblæses.Since the apparatus of the invention not only blows ventilation air in the form of outdoor air into the bedroom, but also uses circulating air which is not completely polluted, the specified standards can be met despite the fact that "too little" outdoor air is blown.
30 Med apparaturet ifølge opfindelsen kan ventilationsluft føres til forskellige dele af boligen i løbet af dagen, * eller dele af dagen, således at en afkøling af f.eks. soveværelset undgås. I stedet kan frisk luft således føres til i den resterende del af boligen, som har fået en øget tempera-35 tur på et tidligere tidspunkt. På denne måde kan der tillades en større øgning af temperaturen i løbet af natten. I løbet DK 170543 B1 3 af dagen er det helt almindeligt, at man befinder sig uden for soveværelset, og det er derfor fordelagtigt at tilføre frisk luft til områderne uden for soveværelserne i løbet af dagen, dvs. at frisk luft føres til disse områder, hvor 5 mennesker er placeret for øjeblikket.With the apparatus according to the invention, ventilation air can be supplied to different parts of the dwelling during the day, * or parts of the day, so that a cooling of e.g. the bedroom is avoided. Instead, fresh air can thus be fed into the remaining part of the dwelling, which has been given an increased temperature at an earlier time. In this way, a greater increase in temperature during the night can be allowed. During DK 170543 B1 3 of the day it is quite common to be outside the bedroom and it is therefore advantageous to supply fresh air to the areas outside the bedrooms during the day, ie. to bring fresh air to those areas where 5 people are currently located.
Ifølge en fordelagtig udførelsesform for apparaturet ifølge opfindelsen er ventilorganerne i ventilationsenheden konstrueret til individuel styring af forsyningen af ventilationsluft til kanalerne. På denne måde kan luften blandes 10 til forskellige rum i overensstemmelse med ventilationsbehovene. Eftersom kanalerne strækker sig fra et fælles trykkammer efter blæseren i cirkulationsenheden, vil den totale strømning i kanalerne være konstant, medens blandingsforholdet mellem ventilationsluft og cirkulationsluft i hver af de 15 separate kanaler kan varieres.According to an advantageous embodiment of the apparatus according to the invention, the valve means in the ventilation unit are designed to individually control the supply of ventilation air to the ducts. In this way, the air can be mixed 10 to different rooms according to the ventilation needs. Since the ducts extend from a common pressure chamber after the fan in the circulation unit, the total flow in the ducts will be constant, while the mixing ratio of ventilation air to circulating air in each of the 15 separate ducts can be varied.
I overensstemmelse med en anden fordelagtig udførelsesform for apparatet ifølge opfindelsen styres ventilorganerne af kuldioxidmålere i et eller flere af opholdsområderne. Mennesker afgiver, som det er kendt, kuldioxid, 20 når de ånder ud, og ved at installere en sådan kuldioxidmåler, eksempelvis i soveværelset, kan regulatorapparaturet styres, således at der fastholdes en acceptabel luftkvalitet i soveværelset.In accordance with another advantageous embodiment of the apparatus according to the invention, the valve means are controlled by carbon dioxide meters in one or more of the seating areas. Humans, as is known, emit carbon dioxide as they exhale, and by installing such a carbon dioxide meter, for example, in the bedroom, the regulator apparatus can be controlled so that an acceptable air quality is maintained in the bedroom.
Ifølge en anden fordelagtig udførelsesform for ap-25 paraturet ifølge opfindelsen forekommer ændringer i forsyningen af ventilationsluft til kanalerne ved hjælp af en omjustering af regulatorapparaturet, som styres af et styreur.According to another advantageous embodiment of the apparatus according to the invention, changes in the supply of ventilation air to the ducts occur by means of an adjustment of the control apparatus which is controlled by a control clock.
Ifølge en yderligere fordelagtig udførelsesform for apparaturet ifølge opfindelsen styres varmeflader af en 30 temperaturtransmitter, hvorved én temperaturtransmitter fortrinsvis er placeret i soveværelset i boligen med henblik på at styre temperaturen af luften, som tilføres soveværelset, og én temperaturtransmitter er placeret i cirkulationsluften eller på et andet passende sted i boligen.According to a further advantageous embodiment of the apparatus according to the invention, heating surfaces are controlled by a temperature transmitter, whereby one temperature transmitter is preferably located in the bedroom of the dwelling to control the temperature of the air supplied to the bedroom and one temperature transmitter is located in the circulating air or another. appropriate place in the dwelling.
35 I overensstemmelse med en anden fordelagtig udførel sesform for apparaturet ifølge opfindelsen styres sætpunkter- DK 170543 B1 4 ne på temperaturreguleringen generelt manuelt, medens den tilladelige temperaturstigning i løbet af natten og det tilladelige temperaturfald i løbet af dagen styres automatisk ved hjælp af et tarifur og et styreur.In accordance with another advantageous embodiment of the apparatus according to the invention, the set points are generally controlled manually on the temperature control, while the allowable temperature rise during the night and the permissible temperature drop during the day are automatically controlled by a tariff clock and et steerur.
5 Ifølge en anden fordelagtig udførelsesform er varme- ft fladerne beregnet til at være elektrisk direkte opvarmede eller vandopvarmede, idet imidlertid elektrisk opvarmede varmeflader er de mest komfortable.According to another advantageous embodiment, the heating surfaces are intended to be electrically directly heated or water heated, however, electrically heated heating surfaces are the most comfortable.
Ifølge endnu en yderligere fordelagtig udførelsesform 10 for apparaturet ifølge opfindelsen er et varmegenvindingsap-paratur indrettet til at formvarme ventilationsluften under benyttelse af den varme udblæsningsluft fra boligen. En forudsætning for en, ud fra et energiaspekt, positiv løsning er, at energi udtages fra den varme udblæsningsluft til 15 forvarmning af den kolde udendørs luft, før udblæsningsluften bortledes.According to yet another advantageous embodiment 10 of the apparatus according to the invention, a heat recovery apparatus is arranged to heat the ventilation air using the hot exhaust air from the housing. A prerequisite for a positive solution from an energy aspect is that energy is extracted from the hot exhaust air to preheat the cold outdoor air before the exhaust air is discharged.
Udførelsesformer for apparaturet ifølge opfindelsen, valgt som eksempler, vil nu blive beskrevet mere detaljeret under henvisning til de vedlagte tegninger, hvor 20 fig. l illustrerer princippet for apparaturet ifølge opfindelsen i en udførelsesform med to kanalrør til luftforsyning, fig. 2 viser, set fra oven, et luftopvarmningssystem med apparaturet ifølge opfindelsen installeret i en bolig, 25 og fig. 3 illustrerer det samme luftopvarmningssystem set i perspektiv.Embodiments of the apparatus of the invention, selected by way of example, will now be described in more detail with reference to the accompanying drawings, in which: 1 illustrates the principle of the apparatus according to the invention in an embodiment with two duct pipes for air supply; FIG. 2 is a plan view of an air heating system with the apparatus according to the invention installed in a housing; FIG. 3 illustrates the same air heating system in perspective.
I fig. 1 er vist en cirkulationsenhed 2 med en blæser 4 og et filter 6. Pilen C illustrerer strømningen af cirku-30 lationsluft.In FIG. 1, a circulation unit 2 is shown with a fan 4 and a filter 6. The arrow C illustrates the flow of circulation air.
To kanalrør 8, 10 strækker sig fra cirkulationsenheden * 2 til lufttransport. Den ene kanal 8 fører til zonen 1, f.eks. soveværelserne, i en bolig, og den anden kanal 10 ¥ til en zone 2 i boligen, dvs. de øvrige dele af boligen. T 35 betegner strømningen af varm forsyningsluft.Two duct pipes 8, 10 extend from the circulation unit * 2 for air transport. One channel 8 leads to zone 1, e.g. the bedrooms, in one dwelling, and the other channel 10 ¥ to a zone 2 in the dwelling, ie. the other parts of the dwelling. T 35 denotes the flow of hot supply air.
I hver kanal 8, 10 er der en varmef lade 12 henholdsvis DK 170543 B1 5 14. Varmefladen 12 kan være styret af en temperaturtransmit-ter 16, placeret eksempelvis i forældrenes soveværelse, og varmef laden 14 af en transmitter 18, placeret i cirkulationsluften eller et passende sted i boligen.In each duct 8, 10 there is a heating surface 12 and DK 170543 B1 5, respectively 14. The heating surface 12 may be controlled by a temperature transmitter 16, for example in the parents' bedroom, and the heating surface 14 of a transmitter 18, located in the circulating air or a suitable place in the dwelling.
5 Kanalen 20 fra ventilationsenheden er forbundet med begge kanalerne 8, 10 for tilførsel af ventilationsluft. Ventilationsluften udgøres af udendørs luft, som forvarmes i en varmeveksler ved hjælp af varme fra udblæsningsluft fra boligen.The duct 20 from the ventilation unit is connected to both ducts 8, 10 for supply of ventilation air. The ventilation air is made up of outdoor air which is preheated in a heat exchanger by means of heat from the exhaust air from the home.
10 I kanalen 20 er placeret et ventilorgan 22, ikke vist detaljeret, som gør det muligt at variere forsyningen af ventilationsluft til de to kanaler 8, 10. Eftersom begge kanaler 8, 10 er forbundet med den samme cirkulationsblæser 4 og de eksterne luftkanaler ikke ændres, vil luftstrømnin-15 gerne i begge kanaler 8, 10 altid være konstant, uanset den forekommende blanding af cirkulationsluft og ventilationsluft. "Kvaliteten" af luften kan således justeres til de faktiske behov i forskellige dele af boligen, som omtalt ovenfor. På en sådan måde kan man være sikker på, at et 20 øvre temperaturniveau ikke overskrides i soveværelset, og at ventilationsluften kan benyttes optimalt for menneskene i boligen. Den generelle omjustering af ventilorganet 22 foretages mest passende ved hjælp af et styreur, hvori tiderne er tilpasset til benyttelsen af huset.10 in the duct 20 is a valve member 22, not shown in detail, which makes it possible to vary the supply of ventilation air to the two ducts 8, 10. Since both ducts 8, 10 are connected to the same circulation fan 4 and the external air ducts are not changed , in both ducts 8, 10 the air flow will always be constant, regardless of the mixture of circulating air and ventilation air. The "quality" of the air can thus be adjusted to the actual needs of different parts of the dwelling, as discussed above. In this way, one can be sure that a 20 upper temperature level is not exceeded in the bedroom and that the ventilation air can be used optimally for the people in the home. The general adjustment of the valve member 22 is most conveniently done by means of a control clock in which the times are adapted to the use of the housing.
25 I fig. 2 er vist et luftopvarmningssystem med en udførelsesform for apparaturet ifølge opfindelsen installeret i en bolig.In FIG. 2 shows an air heating system with an embodiment of the apparatus according to the invention installed in a dwelling.
Udendørs luft indtages i nærheden af taget via kanalen 24 og forvarmes i et varmegenvindingsapparatur 26 af en 30 varmevekslertype, i hvilken varme fra udblæsningsluft benyttes til opvarmning af den udendørs luft, før udblæsningsluften bortledes fra boligen. Varmegenvindingsapparaturet kan være af typen Minivent, som sælges af ABB Flåkt AB.Outdoor air is taken in the vicinity of the roof via duct 24 and preheated in a heat recovery apparatus 26 of a type 30 heat exchanger, in which heat from exhaust air is used to heat the outdoor air before the exhaust air is discharged from the home. The heat recovery equipment can be of the type Minivent sold by ABB Flåkt AB.
Udblæsningsluften 28 tages fra skabsområder, toilet-35 områder, køkken og badeværelser.Exhaust air 28 is taken from cupboard areas, toilet-35 areas, kitchen and bathrooms.
Ventilationsluft i form af forvarmet udendørs luft 6 DK 170543 B1 føres via kanalen 20 til kanalerne 8, 10. I kanalen 20 er, som nævnt ovenfor, installeret et justerbart ventilorgan. Cirkulationsenheden 2 kan udgøres af en såkaldt Termovent-enhed, som sælges af ABB Flåkt AB.Ventilation air in the form of preheated outdoor air 6 is passed through duct 20 to ducts 8, 10. As mentioned above, in duct 20 an adjustable valve member is installed. The circulation unit 2 can be constituted by a so-called Thermovent unit sold by ABB Flåkt AB.
5 Via opvarmningsenheder 12, 14, filtre 30, 32 og støj- , dæmpere 34, 36 føres udendørs luft til soveværelserne henholdsvis andre områder i boligen, se også fig. 3, som viser systemet i fig. 2 i perspektivisk afbildning. TDI, TD2 og FDl indikerer forskellige forsynings- og udblæsningsluft-10 indretninger.5 Via outdoor heating units 12, 14, filters 30, 32 and noise, dampers 34, 36, outdoor air is supplied to the bedrooms and other areas of the dwelling respectively, see also fig. 3, which shows the system of FIG. 2 in perspective view. TDI, TD2 and FD1 indicate different supply and exhaust air devices.
Ovenfor er én udførelsesform med to kanaler til luftforsyning vist og forklaret. Apparaturet ifølge opfindelsen kan naturligvis fremstilles med mere end to kanaler til forsyning af luft til forskellige zoner.Above, one embodiment with two ducts for air supply is shown and explained. The apparatus of the invention can, of course, be manufactured with more than two ducts for supplying air to different zones.
15 Ved den ovennævnte udførelsesform er cirkulations enheden og luftopvarmningsenheden, som udgøres af varmefladerne 12, 14, yderligere illustreret i form af to separate enheder, blandt andet for at gøre illustrationen mere klar.In the above embodiment, the circulation unit and the air heating unit, which is constituted by the heating surfaces 12, 14, are further illustrated in the form of two separate units, among other things, to make the illustration more clear.
I praktiske udførelsesformer for apparaturet ifølge opfindel-20 sen kan cirkulations- og luftopvarmningsenhederne imidlertid være samlet til én enhed.However, in practical embodiments of the apparatus of the invention, the circulation and air heating units may be assembled into one unit.
